Answer:
No, it is not.
Explanation:
One <em>x </em>value (-3) has more than one corresponding <em>y </em>value (1 and 0). In a proper function, each <em>x </em>value has one and only one corresponding <em>y </em>value.
y = 2x - 3/4
Step-by-step explanation:
Adapt the slope-intercept form: y = mx + b.
Making the indicated substitutions, we get
Hello,
5x² = 90/2
5x² = 45
x² = 45/5
x² = 9
x = √9 or x = -√9
x = 3 or x = -3
